Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, and specifically to an automatic positioning device for laser cutting. Background Art

[0002] Laser cutting machines still have some problems during the cutting process, especially the large amount of waste chips and thermal effects generated when cutting workpieces, which have a particularly significant impact on processing quality and efficiency. In the traditional processing flow, the workpiece is directly placed on the support plate for positioning, which seems direct and simple, but it hides hidden dangers. Especially when processing workpieces with cavity structures, if the cavity is directly in contact with the support plate facing down. On the one hand, the high temperature generated by laser cutting is concentrated on the workpiece, which can easily cause the bottom of the workpiece to deform due to heat, especially on the support plate material with poor heat conduction, the hot zone expands, affecting the dimensional accuracy and shape stability of the workpiece. On the other hand, the waste chips generated in the cutting cavity are difficult to discharge smoothly and accumulate in the cavity, which not only hinders the continuous cutting path of the laser beam, but also may damage the equipment, affect the cleanliness of the cutting surface, and increase the difficulty of later cleaning.

[0045] In this embodiment, in order to solve the problems in the related art of directly placing the workpiece on the support plate, which will increase thermal deformation and heat-affected zone, and inconvenience in chip removal, the frame 100, as the main structure of the device, provides a stable installation platform. The frame 100 is the foundation of the entire system, ensuring the stability and durability of the device and providing installation space for subsequent components. The support frame 200 is on the frame 100, used to directly carry the workpiece, ensure the stability of the workpiece, provide accurate support for the processing process, and avoid the movement or deformation of the workpiece. At the same time, the support frame 200 is designed to separate the workpiece from the debris area, effectively isolate the heat influence, and reduce thermal deformation and debris interference.

[0046] The cutter 300 is movably arranged on the frame 100. The cutter 300 is configured as a laser cutting head or a laser emission source, a moving mechanism, and the cutter 300 accurately moves according to the instruction to cut the workpiece, thereby realizing automatic cutting.

[0070] There are a plurality of wiping members 900 , which are respectively disposed on a plurality of supporting blocks 223 . The wiping members 900 are slidably disposed on the longitudinal guide rail 120 and the transverse guide rail 110 .

[0071] In this embodiment, the support block 223 is not only slidably arranged at the top of the support column 222, but also has a slide groove 224, which is arranged at intervals. The design of the slide groove 224 makes the support block 223 slide more flexibly on the support column 222, and increases the adjustment range. The block 700 is slidably arranged in the slot 225, and one end of the elastic member 800 is fixed on the block 700, and the other end is in the slot 225. The introduction of the elastic member 800 provides a sliding rebound force for the block 700, so that the block 700 clamps the support column 222. Several wipers 900 are correspondingly arranged on several support blocks 223, and the wipers 900 are slidably arranged on the longitudinal guide rail 120 and the transverse guide rail 110.
